To all 'whom it may concern:

Be it known that I, HERMAN H. Sr-EOK, a citizen of the United States, and a resident of the city of Cincinnati, Ain the county of Hamilton and State vof Ohio, have yinvented certain new and useful Improvements in Came-ras, of which the following is a full, clear, and exactdescription, reference being had to theaccompanying drawings, forming part of this specification.

My invention relates to film cameras.

wherein a roll of sensitized film is led behind a lens and shutter and wound from,

oneroll to another so as to bring a section of given dimensions into position forexposure, for each photograph that is to be taken.

It' is the object of my invention to pro-l vide a device for drawin the film from the storage roll onto the recelvi'ng roll of a film camera, whereby a turn of a crank acco1nplishes one complete movement of a given section of film, and whereby in addition' a snap' shot exposure of the film section is made.

This object, with the advantages noted, and various others as will be detailed below, I accomplish by that certain construction andarrangement of parts to behereinl The film roll, or storage roll 'is mounted at after more specicallylpointed 4out and claimed.

In the drawings, Figure 1 is a central Avert1cal section of the Vdevice taken looking toward the film y winding crank.

Fig. 2 is a rear elevation of my new de.

vice.

Fig. 3 is a side elevation? of the camera with my attachment mounted thereon.

Fig. 4 is a perspective View of the bracket for the shutter releasin device.

Fig. '5 is a longitu inal section of the shutter releasing device with the flexible portion thereof 1n elevation.

My device is shown as attached toa camera having a bellows 1, a door 2, a shutter and lens holder 3, and a box portion 4. This box ortion is of the usual type for use with Elms, and has spindles for the usual storage and receiving film-rolls, at 5 and.6, and a handle 7. T e ordinary film attachments are not used when my attachg ment is mounted on the box, and the new.

device is shown asattached 'in the manner of the Iilm pack adapter of the camera art Across'theJ inner side 13 ofthe attachment box are cut the slots 14 and 15 for' the pas-V 4 sageof the film 16. In the upper slot 14 is mounted the corrugated feed idlerroller 17 on metal plates 18, 18, screwed to the 4'back of the side 13. These plates have suflicient spring in them to yieldably holdvthe corrugated roller against the feeding-disks to be hereinafter described. Iny the lower slot is mounted the idler roller 19, in any desired manner, as it need not be yieldable.

On a fixed plate 20 near the lower slotI and inside of the box is rotatably secured a wing-headed screw21, the head of whichengages a slot in the, end of the film storage roll 22, and the other end of the' said rolll engages a stud 23 on a spring plate 24 secured tothe back ofthe side 13 of the box.

this point, in loading the camera, and the feeding devices draw' theflm from this roll forwardly over the idler 19, up along the;v fiat surface of the -box side, and thence to the receiving roll.

'Mounted on a spindle 25 adjacent the corrugated feed roll above mentioned, are a pair of friction disks 26 which bear against said roll. Secured to the left hand ldisk is a ratchet wheel 27 Awhich is engaged by aI spring finger 28 mounted on the box wall. This ratchet device enforces a clockwiserotation of the friction disks and their spindle. To the other friction disk isl secured a gear wheel 29 which meshes with an idler gear'29 mounted on the box. Thisulatter gear has secured to it a friction wheel30 `which contacts with a friction wheel 31`op eratively connected to the receiving -r'oll as will be described. v

The receiving roll 3.2 is mounted at one end by itsA engagementover a stud 33 on a sprlng plate 34 mounted on the box. The other end of the roll enga esio'ver the`l .wing head 35 of a pin 36.- `T 'spin carries they friction 31 rheretofore men? tioned and lies in slots 37 in a pai-r of plates 38, 39.. The plate 38 is the inner plate and extends out over a cored-out portion 40 of The pla-te 39 is bent inwardlyat its .outer end so as to extend the 'side of the box.

outoverfthe frictionwheel 30 and serve as" a guard therefor. The slots in the plates` referred to vextend at a slight angle from the vertical inthe .direction of the frict1on disk 30 and serve to press the small friction disk 31 on the pin 36, that is now' being described, against this friction disk yieldable one.. The springs 41, 41, are provided, which press against the pin 36 along the sideof each ofthe plates. The angle direction of the slots is such as to lie directlyv in line with' the pull of the iilm as 1t 1s Woundvon 'the receiving roll.

Idler yrolls. 42, 43 are mounted between the sides of the box, and a guard plate 44 isl secured to the side 13 of the box and extends up along these idlers. 4The film passes ,over these idlers and Without the guard plate might belly-out and .become caught in the storage roll, which is immediately below it.

The crank and handle 45 is connected to the spindle of the main friction disks 26 and is employed to turn the receiving roll and the various feeding devices through lthe medium of the friction disks and gears re- .ferredl to. It is necessary in any film camera to draw a given amount of film by the position for exposure t for each photograph taken, and a-ccordingly the parts herein are so proportioned that one turnof the crank 45 will effect one complete movement of the film for 'one picture. This is done,- however, with due provisionA for a certain' amount of free movement of the spindle 25 to which the crank is connected, so that the` operator maytell by the free movement that the crank has completed one complete turn.

and .to allow him some space Within which to stop the movementl after each turn which Will not feed `the iilm.- For'this purpose y the friction disks 26 have the flattenedporcorrugated roll '17 and the friction disks 26.

From theseuit passesalong'the side wall of theA box, over the'idlers 42 and 4.3, and is positively ywound up onthe receiving roll. A turning'of the ycrank operates the friction that the contact is a and kit-he receiving roll thereby accomplishing the positivo movements rev ferred to.

` It will be noted that yieldable contact is provided foi` all friction transmission mem- "bers. This insures that the film will not l get .caught or clogged at any point andlthat the movementl will l be y free and sure.

roller 48 mounted on a hino'ed arm 49, is

maintained against the'surfcace of the ref ceiving roll by means of a spring 50. The film winding ,devices'now described are of value in themselves Awithout the other parts of my machine, inasmuch as they provide` a` quick and easy wayr` of. changing `the film after each exposure, l p. f

It 1s deslred to. have some dlrections .printed on lthey side of. the box,.under the crank, to indicate the vpoint where a comv plete movement of the film for one exposure 1s` accomplished.v These are not shown, but it will be understood that any desired Wordy can be stamped. oriothe'rwise formedon the side of the box at the point where they han,

dle is to stop after each movement;v

As was'stated above, the crank 45 is .also used to release the shutter ofthe camera.

This is accomplished' by the crank, while itis idle as far as tlielm winding rolls are con-Y cerned. The flattened I portions mentioned are so arranged thatl when the crank is about to set off the shutter to expose a portion of film, the crank has just come to idle position, and that after setting oil' the shutter there will still be a certain amount of' free movement left, to serve as yan element of safety.

The so-called antinous shutter release is preferablyused by me, as its structure easily adapts itself to actuation by the crank. Sucha release (Fig. 5) has ailexible tube 51-within which is a wire 52.I This Wirey extends out through a union coupling for the shutter box and has a small plunf ger 52a at its len d. to release the shutter.

The bellshaped end piece 53 at the other end of the tube is ordinarily used for a finger hold in the operation of the release, and a plunger 54 connected to the wire is employed to push the wire along within the tube, thereby forcing out the small plunger at the other end. A spring 55 mounted in 'the end piece 53. serves toy maintain the plunger 54 in mall-y. f y

The bracket 56, having the beveled slot 57 to `fit this bell-shaped end referred to, is mounted on the outside' of the attachment an extended position, norbox, b means of a baseplate 58. This base plate as an ear 59 to which is hinged the clamping finger 60.v This finger has a slot per edge of the bell-shaped end piece as it ich will fit down over the shaft. of the lplunger 54, .a top lflange 62 (Fig. 4)y whichl.l`

as asegmentalcut 63 in it to clear the up? stands in` the bracket, and a spring latch linger 64 to ride over the end of the bracket plate and engage a slot 65 therein. Mounted pivotally on the attachment box adjacent I to the bracket is a swinging plate 66, which is preferably formed with asleeve 67 that is Journaled on a pin 68 inserted in the side of the box. The one end of this plate is in contact With the plunger 54, and is thusl held normally with its other end abutting against the ear 59 above mentioned. This latter end of the plate is alsosin the path of the crank and located so as to contact with it just after the crank has reached idle position as described. The movement of the crank vwill swing the plate along .With it and cause its other end to press in the plunger to release the shutter.

The crank has its end 69 cut slantingly so as to slide over the plate as soon as the shutter is released and the plate will than may be used for other purposes than the mere rapid film exposures mentioned. One film portion at a time may be exposed with long or short intervals of time between exposures as desired. The advantages of easy film turning and the added advantage of the operator always knowing that, if his crank is in `a certain position, the film that is in front of the shutter is either exposed or not exposed dependent upon such position, are apparent. As mentioned heretofore, directions may be stamped or pasted on the attachment box to indicate the various position of exposure or nonexposure.

The device as described is shown as operating With-a special type of shutter release, but it will be understood that I do not desire to be limitedto this one use alone, inasmuch as it is *believed to be broadly new to release a shutter in substantially` the manner' described. References to specific roller mounting and the use of various mechanical expedients of Which there are equivalents Well known to those skilled in the art, are not intended as limitations of novelty except as stated in the claim.

Having thus described my invention, What I claim as nen and desire to secure by Letters Patent, is

In an attachment for film cameras, a box, means for mounting a film therein, and mutilated feeding mechanism therein for intermittently feeding the film past an -exposure point, a handle for said' feeding mechanism exterior the box, a shutter release for the camera located on the outside of the box in the path of the handle, said handle adapted -to set off the shutter releast` by contact therewith during a nonfeeding. portion of its movement.
